With various automatic welding machines, small tanks or large tanks with circular welds up to Ø 3.3 m and longitudinal welds up to 12 m can be produced automatically. Pipelines can be manufactured by orbital welding in a closed gun, including documentation of the weld seams. Ground, mirror polished or electropolished surfaces with defined roughnesses up to a maximum of Ra<=0.2µm are possible.
